The official Go client library for Prometheus, providing APIs for instrumenting application code with metrics and for querying the Prometheus HTTP API. It supports counters, gauges, histograms, and summaries, and can export metrics via OpenTelemetry OTLP.
Use cases
- instrument a Go application with Prometheus metrics
- expose counters and histograms from a Go HTTP server
- query Prometheus data from a Go program
- export Go app metrics via OpenTelemetry OTLP
- add custom business metrics to a Go microservice
When to choose
- you need standard Prometheus metrics instrumentation in Go
- you want the official, widely adopted Prometheus client
- you need to bridge Prometheus metrics into OpenTelemetry pipelines
When to avoid
- you are instrumenting a non-Go language (use the language-specific client)
- you need a full metrics collection and storage system (use Prometheus server itself)
- you rely on the HTTP API client and need strict API stability guarantees
